Pro VCF Eurorack Filter First Look [Demo #1]

The Pro VCF is a faithful adaptation of a well-known 4-pole synthesizer filter in Eurorack.
The core of this design lies an Alfa AS3320 filter chip based on the original Curtis.
Let's put the Pro VCF through some paces.

Announcing the Pro VCF Eurorack Module

Coming next week: the Pro VCF.
The Pro VCF is a faithful adaptation of a well-known 4-pole synthesizer filter in Eurorack.
The core of this design lies an Alfa AS3320 filter chip based on the original Curtis. Countless synthesizers used the 3320: Sequential Pro One, Prophet 5 rev 3, Drumtraks, Crumar Trilogy, Stratus, Elka Synthex, some Fairlight CMI, Linndrum, Oberheim OB-8, OB-Xa, PPG Wave 2
At full resonance the Pro VCF can self-oscillate.

FEATURES
Two selectable filter slopes: original 24 db/oct, and 12 db/oct.
Two voltage controlled input jacks for frequency CUTOFF w/ signal attenuators.
A voltage controlled input jack for RESONANCE w/ a signal attenuator.
Two signal input jacks w/ individual attenuators. At full clockwise, these inputs can overdrive the filter from most eurorack oscillators and audio sources.

My DC571 Lo-Fi Dual Compressor Has Returned

Bringing this one back out of retirement.
Currently available in my Reverb Store.

There's nothing like an Analog Compressor to warm up your sound.
Make percussion grooves a little punchier, bass a bit snappier, and glue the mix together.
My DC571 module has TWO fully independent channels of no-nonsense audio compression made especially to give your Eurorack some of that subltle swingin' groove.
You can even cascade channel 1 output into channel 2 for even more compression.
The DC571 uses an 80s design dual compander chip (still in production) to work its mojo.
Each channel has controls for input level attenuation, output make-up gain, and a true bypass switch.
The DC571 is hand-crafted in USA in limited quantities.

Transistor-82 Lo-Fi Oscillator FM Demo #2

I was contacted by Frederic on Reverb about my Transistor-82 analog percussion module.
He was wondering about the range of the oscillator pitch CV input.
And what it sounds like with oscillator FM.
Be warned, there are some pretty rough sounds ahead.
Audio recorded direct to Tascam DR-05, no added effects.

Infusor-X VC FX Bus Switch / 10-Ch Active Audio Mixer

Summer is about to get a little bit hotter.

It's a mixer, it's a VC FX bus routing switcher.

Erica Synths Sample Drum USER REVIEW Eurorack [Pt. 2/2]

Today I am continuing my user review of the Erica Synths Sample Drum. I will be covering the On-Board Effects, CV Mapping, Performance Mode, Saving Projects, and global settings. Along the way I'll try a couple of interesting experiments using the features covered. Be sure to hang around for the end of the video where I'll share my final thoughts.

Audio samples were recorded and processed in ocenaudio.

Erica Synths Sample Drum USER REVIEW Eurorack [Pt. 1/2]

Today I am giving another new product user review, this time the Erica Synths Sample Drum Eurorack Module. The Sample Drum is described as an easy-to-use, two voice, modular sample player designed with percussion and loops in mind. So how does the Sample Drum perform as a loop playback sampler? Can it be as crunchy as your Akais or Emus? Let's see.

Recorded direct to Tascam DR-05. No outboard effects nor processing of any kind.

GSE 4023-VCF Filter Demo #3 Saturated Drums

In a previous video I showed how the 4023-VCF has some lovely saturation with synthesizer sounds.
Today I will be running some percussion though the filter. In most cases, when the input slider is above 60% the filter input will start to become overdriven. Resulting in a warm and fuzzy distortion.
I'll be using control voltages to use the saturated filter as a gate,which can change-up the grooves.

Audio recorded direct to Tascam DR-05.
No additional effects other than what you see.
